FIDP: A Novel Architecture for Lifting-Based 2D DWT in JPEG2000
In this paper, we propose a deeply parallel architecture called Fragment-based Interleaving Dual Pipelines(FIDP) which can exploit all parallelisms in Lifting-based 2D DWT algorithm. FIDP adopts a fragment-based samples consumption policy and consists of two row processors and two column processors....

Summary: | In this paper, we propose a deeply parallel architecture called Fragment-based Interleaving Dual Pipelines(FIDP) which can exploit all parallelisms in Lifting-based 2D DWT algorithm. FIDP adopts a fragment-based samples consumption policy and consists of two row processors and two column processors. These processors are organized as interleaving dual pipelines to operate effectively. FIDP takes N2/4+N/2+1 cycles to finish a N×N 2D DWT while requires only 5N+2 buffer. |
